Sule\-X is an automatic sulcis extractor, matcher and labeler.

It supports the .brn format and the .obj format paired with a feature map coded in a .txt file.  \subsection{Interface and interactions}\label{howtosulex_iterractsulex}
The interface is very simple and composed of two windows : one for the source brain, one for the target one. Both windows display the source (resp. target) brain mesh in a choosen mode.

The brain display mode can be changed keying the 'v' letter for VERTICES display mode, 'e' for EDGES display mode or 'f' for FACES mode.

The target window displays its brain sulcis in different colors.

The source window displays every sulcis of its brain in the color of its match in the target brain.\begin{itemize}
\item When a sulcus is selected, it is displayed in white. (See the picture top.)\item A small information box pops up when a sulcus is selected by the user, containing the name and the color in RGB ( in [0,1]X[0,1]X[0,1] ) of the selected sulcus. (see picture on top, region highlighted in red).\end{itemize}


Interaction with the brain is done with the mouse events :\begin{itemize}
\item The left click is attached to a trackball that permit to rotate the brain.\item The right click is attached to a picking mode so that the user is permited to select the sulcus he wants to select with a simple click.\end{itemize}
\subsection{Visualize and get informations}\label{howtosulex_visualize}
The goal of this software is to match automatically the different sulcis of the source brain onto the target one. The result of this matching is shown by the color similarity between the two windows. If the source brain is compared to a pre-labeled brain, it will be also labeled in an automatic way. To get informations about a sulcus, just right click on it and have a look to the left top information box : you will find its color in a RGB format and its automatic label if the target has been labeled before the usage.\subsection{Loading files}\label{howtosulex_loadsulex}
Sule\-X is used as follow : it takes in parameter the source brain surface in a .obj (wavefront) format AND its map in a .txt format, then you have to give in parameter either a .brn brain file or the target bmesh in a .obj (wavefront) format and its map.\subsection{See also}\label{howtosulex_seealsosulex}
You should take a look to the Sulcla\-B (Sulcis Labeler) script which is at a higher level than the Sule\-X software (parameters management, automatic map computation when needed, automatic comparison to averages).
